• question_answer Which of the following reaction is not feasible [CBSE PMT PMT 2002] A) $2KI+B{{r}_{2}}\to 2KBr+{{I}_{2}}$ B) $2{{H}_{2}}O+2{{F}_{2}}\to 2HF+{{O}_{2}}$ C) $2KBr+{{I}_{2}}\to 2KI+B{{r}_{2}}$ D) $2KBr+C{{l}_{2}}\to 2KCl+B{{r}_{2}}$

Solution :

$2KBr+{{I}_{2}}\to 2KI+B{{r}_{2}}$ Iodine is a less electronegative compare to Bromine hence iodine does not change $B{{r}^{-}}$to $B{{r}_{2}}$.
